| 摘要 | The oxidation of a Sm(Co0.68Fe0.22Cu0.08Zr0.02)(7.5) magnetic alloy deposited with a thin Al2O3 film has been studied. The Al2O3-coated alloy exhibits almost no oxidation at 500 degrees C and only forms a few-micrometers-thick internal-oxidation-affected zone (IOAZ) at 600 and 700 degrees C for 20 h exposure to air. The effect of the Al2O3 film on the oxidation degradation of magnetic phases of the alloy is disclosed based on microstructural characterizations of the IOAZ. The result also shows that the Al2O3 film offers better protection than the Cr2O3 film reported previously. (C) 2014 Elsevier Ltd. All rights reserved. |
